Benefits of technology

[0023]The vision system may include an optical output device. The processor may be configured to control the optical output device to output information indicating an object in the at least one image which has a feature descriptor matching one of the retrieved geo-referenced feature descriptors. This allows information to be specifically assigned to objects in the user's field of view.
[0024]At least one of the geo-referenced feature descriptors may have associated position information that includes height information. The pr

Problems solved by technology

There are various difficulties associated with automatically performing object recognition.
However, this represents a considerable challenge.
While techniques applied to prior art vehicle vision systems may be useful to reliably classify objects into one of a limited number of classes, such as for detecting

Embodiment Construction

[0057]Embodiments of the invention will be described with reference to the drawings. While some embodiments will be described in the context of vehicle vision systems, the systems and devices of various embodiments may be employed in a wide variety of applications. The features of embodiments may be combined with each other unless specifically stated otherwise.

[0058]According to embodiments, geo-referenced feature descriptors, which may be combined to form geo-referenced feature vectors, are utilized for object recognition in an automated vision system. As used herein, the term “geo-referenced” refers to a quantity that is associated with at least a pair of coordinates specifying the lateral position of an object associated with the quantity. For example, a geo-referenced feature descriptor is a feature descriptor that is associated with at least a 2-tuple of coordinates, which represent a position or position estimate of the object represented by the geo-referenced feature descript...

Abstract

A vision system comprises a camera that captures an image and a processor coupled to process the received image to determine at least one feature descriptor for the image. The processor includes an interface to access annotated map data that includes geo-referenced feature descriptors. The processor is configured to perform a matching procedure between the at least one feature descriptor determined for the at least one image and the retrieved geo-referenced feature descriptors.

Description

CLAIM OF PRIORITY[0001]This patent application claims priority from EP Application No. 10 014 418.7 filed Nov. 9, 2010, which is hereby incorporated by reference.FIELD OF TECHNOLOGY[0002]The invention relates to a vision system, and in particular to an automated vehicle vision system.RELATED ART[0003]Machine vision is practiced in a wide variety of systems. Recently, applications that employ vision systems in automotive environments have been contemplated for safety or other applications. In particular, image recognition in automotive systems may be employed for various purposes including navigation or aiding the driver in controlling a vehicle. For these purposes, images of a neighborhood of the vehicle are recorded, frequently by a camera onboard a vehicle, and analyzed in order to identify objects (e.g., roads or road edges), that may be of relevance for navigation purposes or for controlling the vehicle. Once an object has been identified or recognized in an image, specific proc...
